IMPROVEMENT IN ANTl-RATTLING SPRINGS FOR THlLL-COUPLINGS.

' Specificationforming part of Letters Patent No. 196,554, dated October 30, 1877 application filed October 12, 1877.

To all whom it mag concern:

Be it known that-I, HORACE BEARD, of Wilton, in the county of Hillsborough'andSta'te of New Hampshire, have invented certain new and useful Improvements in Springs for Thill- Couplings, and I do hereby declare the following to be a full, clear, and exact description of the invention,"such as will enable oth- .vent carriage thills and poles from"rattling..-

It doesnot require a special coupling for its accommodation, but can be used in couplings of various kinds. I

can be inserted without taking off the-safety It is so constructed that it strap and without uncoupling the thillan operation which necessitates the removal of I the wheel in order-to withdraw the couplingbolt. The manner of its insertion is peculiar to itself, and gives it a superiority over other coupling-springs.

The following-is a description of my invention and of the mannerjof its insertion, reference being had to the'acc-ompanying drawings.

. Figure 1 is a perspectiveview of my invention, which .consists of ametallic spring which rises nearly-in the form of a half-circle until it reaches the highest point, where it bends abruptly, and is folded downward upon itself along the convexsurface until it reaches the place of the greatest swell, where it assumes a wedge-like shape, and has a horizontal concavity across its front. Fig. 2 is a perspective view of a thill-coupling with my invention in position. Fig. 3 is a longitudinal section of the same.

A and B are the axle and bed-piece, around which is the clip 0, from which project two arms, D, between which is the eye E, through which passes the bolt F, on which it turns. G is the spring, which is in contact with the clip at H and J and presses forcibly against the eye This pressure keeps the spring in place, and prevents all rattling of the thill.

To insert the spring, its lower end is placed in the opening between the clip and eye, and pressure or percussion upon the top of the wedged-shape portion forces it into position.

Having thus described my invention, I claim A metallic spring which rises nearly in the form of a half-circle until it reaches its highest point, where it bends abruptly, and is folded downward upon itself along the convex surface until it reaches the place of the greatest swell, where it assumes a wedge-like shape, and has a horizontal concavity across its front, substantially as shown and described, to be used in the manner and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of O0- tober, 1877.

. HORACE BEARD.
